Jactus!

The Game of Emperor's

Although gambling was frowned upon in Roman society, there were certain times particularly during festivals such as the Saturnalia, when laws were relaxed and betting was allowed.

Jactus was a popular Roman dicing game once enjoyed by the emperor Augustus. The historian Suetonius Tranquillus recorded the outline of the game, reputedly quoting from a letter written by Augustus himself:

"I dined, dear Tiberius, with the same company ; we had besides as guests Vinicius and the elder Silius. We gambled like old men during the meal both yesterday and today ; for when the dice were thrown, whoever turned up the 'dog' ¹ or a six, put a denarius in the pool for each one of the dice, and the whole was taken by anyone who threw the 'Venus' ²." (Suetonius de vitae caesarum, Augustus, LXXI.2)
  1. Canis 'the dog' occurs when all dice show a 1.
  2. Venus occurs when the dice all show different values.
